The example is "typical" in the sense that it is not too rigorous on one hand and not too simple on the other hand. The Tutorial Manual serves as a guide by: i) assisting the user with the input of data necessary to solve the boundary value problem, ii) explaining the relevance of the solution from an engineering standpoint, and iii) assisting with the visualization of the computer output. An attempt has been made to ascertain and respond to questions most likely to be asked by first time users of SVSOLID. 1.2 A Two-Dimensional Example Model The following example introduces some of the features included in SVSOLID. The example problem sets up a model of a simple slope with two foundation loads applied. A water table is present. The purpose of this model is to determine the stress conditions in the slope due to applied loads and the magnitude of displacement under each footing. The model dimensions and material properties are provided below.

The steps fall under the general categories of: a. Create model b. Enter geometry c. Specify boundary conditionsSVSolid Tutorial Manual 8 58of d. Apply material properties e. Specify model output f. Run model g. Visualize results a. Create Model Since FULL authorization is required for this tutorial, the user must perform the following steps to ensure full authorization is activated: 1. Plug in the USB security key. 2. Go to the File > Authorization dialog on the SVOFFICE Manager. 3. Software should display full authorization. If not, it means that the security codes provided by SoilVision Systems at the time of purchase have not yet been entered. Please see the the Authorization section of the SVOFFICE User's Manual for instructions on entering these codes. The following steps are required to create the model: 1. Open the SVOFFICE Manager dialog. 2. Create a new project called Tutorial by pressing the New button next to the list of projects. 3. Create a new model called UserTutorial2D by pressing the New button next to the list of models. The new model will be automatically added under the recently created Tutorial project. 4. Select the following: · SVSOLID for Application · 2D for System, · Steady-State for Type, and · Metric for Units. The user should also set the World Coordinate System to ensure that the model will fit in the drawing space. The World Coordinate System settings can be set under the World Coordinate System tab on the Create Model dialog. 1. Access the World Coordinate System tab on the Create New Model dialog. 2. Enter the World Coordinates System coordinates shown below into the dialog. x-minimum = 0 y-minimum = 15 x-maximum = 77 y-maximum = 57 3. Click OK to close the dialog.SVSolid Tutorial Manual 9 58of The workspace grid spacing needs to be set to aid in definin
